My invention relates to bags or envelopes, sometimes called handle bags, in which. by openings in the end of the container. convenient: means for holding it with the hand or'with oueor more fingers are provided for.

Ilnrelopes aud bags of this kind are constructed today in such a. way that. the. supporting reinforcements and the locking means are one part. and easily tear in at the edges folded over; such bags have also the disadvantage of gapping open along` a. eertain width at. the top, ereu when locked by the means provided i'or this purpose..

I have succeeded to overcome these disad- \f'anlages by my improvement, the ol jects of which are, first, to prot-ide supporting and locking means on the. end of the bag by incisions into the end ot the flap: second, to have locking meauswhich engage parts separated from the edge along which the bag is supported; and third` to provide such a. bag with (laps which tightly hold together the top edges of the front and ot. the back of the bag.

I attain these objects by constructing bags and envelopes ot this kind in a manner shown in the accompanying drawings, in which,-

Fig. 1 shows the blank paper stamping from which I make my bag.

Fig. 2 is an end View ot a bag closed by my novel means.

Fig. 3 is the same bag, seen from the front.

Fig. 4 is a sectioned side View of that bag with exaggerated cross-sections of the paper.

Fig. 5 is a sectional view of that bag, when open.

Similar numerals refer to similar parts throughout the various views.

In Figure 1, I have dotted the lines along which the paper is folded in making up the' bag and also those lines along which the flap is folded when the bag is to be closed. Along lines G and 7 the paper is folded to make up the bag, edges 8 being glued together' alter the paper has there been doubled up upon itselt, and has been folded along line 7. However, I do not limit my invention to bags folded in this particular manner but I may also use it for bags with a single seamlength- Wise and a seam at the lower end. By paper layers 9 the two ends ot the blank are reinforced and it is through these reinforced parts ot' thebag that I cut theoblong windows l0 and 1 l in the. front and the back. 1'e speetively, of the bag. These windows fit on 3 thevery endfof the tlapinwh'ieh lrvsuitable incisions the .supporting tongue l2' and the paper.

lVhen the finished bag is closed by bending o rer the tiap along line ,llt the. various tongues 12, 13 and 13 come to lie on top ot' the windows l0 and 11. It I push the lock tongues 13 through the windows 1l and l() 'ot' the bag and crease them along lines l5 they will lock the bag and the Wings on the tongues will prevent the,bag from opening up again although the tongues may not remain fully bent back in creases 15. The advantage ot' this o\-'erlapping locking arrangement -can readily be se'en from Figure 4 in which the edges 1G and 1T otl the windows in the t'ront and in the back of the bag, respectively, are tightly held together by said lock tongues.

After the bag has thus been locked I bend over the supporting tongue 12, creasing it along line 18 over the top edges of the windows; thiscovers up those edges of the win dows so that they cannot eut the hand or fingers ot the person carrying the bag.

It is, however, clear from my description that I do not require the central tongue lor holding the front and back together. I may fomit that tongue and still the edges 1G and 17 are held tightly together by the Winged lock tongues 13.

I claim:

1. In a paper bag comprising a front, a back, and a Hap extending from the top of said front and bent over part of said back, registering oblong windows, with short side. edges and long top and bottom edges, in said liront and in said back, and Winged lock tongues forming part of said iap, extending from the sides over said windows and narrowed at their bases to awidth clearing the said short side edges.

2. In a paper bag comprising a front., a back, and a flap extending from the top of said front and bent over part of said back, registering oblong Windows, with short side edges and long top and bottom edges, insaid front and in said back, winged tongues on saidlap adapted to be bent over said side edges through said windows and to engage said top and bottoni edges on said front., and 4a central-tongue on said Hap between said winged tongues, adapted to he bent oveisaidl top edges ot said windows.

` winged lock tongu'esl-l are'shaped out of the edges an ,tongues forming part of said flap, extending from the sides over saidwindows and` narrowed at their bases to a IWidth clearing the said short side edges insertably registering with said windows and a centralD tongue. forming part of said flap and extending l0511er said top 'edges into said Windows. i f

4. In a paper,bageomprlslng` a `frontta 2back, and'a flag) extending from the top of said front and;

ent over) part of said back, registering oblong Wlndows, with short side v4edges and long top and bottom edges, in said -front "and in said back, and winged lock .tongues forming part of said flap, extending from the sides over said Windows and narrowed at their bases to a width clearing said short side edges, arranged to lock mto said Windows.-
